GEORGE CORNl/VALL, OF NEW YORK, N. Y.

BOOK- COVER.

SPECIFICATION forming part of Letters Patent No. 431,876, dated July 8, 1890.

Application filed July 10, 1889- Serial No. 31,7,009. (N model.)

To all whom it may concern:

Be it known that I, GEORGE CORNWALL, a a citizen of the United States, residing in the city of New York, in the county and State of New York, have invented certain new and useful Improvements in Book-Covers,of which the following is a specification.

My invention has for its object the production of an improved double flexible bookcover adapted to be applied to the ordinary stiff or flexible covers of books, magazines, &c., (for protecting them,) which shall have unbroken stiffened stitched edges, be capable of ornamentation, be readily and easily applied or taken off of the-book, magazine, &c., and be adapted to receive additional leaves for advertising purposes.

To this end my invention consists of an improved construction of double cover manufactured, preferably, of a single sheet of Na nila paper, having its top and bottom edges folded over and its outer flaps then folded in, the whole being then held together by continuous seams of stitchingpassing through the four thicknesses of paper at the top and bottom of the cover, so as to provide stiffened protecting top and bottom edges.

Referring to the accompanying drawings, which form a part of this specification, Figure 1 is a perspective inside view of the preferred form of my cover. Fig. 2 is an outside view of the blank. Fig. 3 is an inside View of the same partly folded. Fig. 4 is an inside view of the blank fully folded. Fig. 5 is an inside view of the stitch ed blank forming a completed cover. Fig. 6 is a sectional view of a book having my cover applied, the section of the cover being taken at the part indicated by the dotted lineX X, Fig. 5. Fig. 7 is a similar view of aportion of abook-cover having my improvement applied, the line of section through the cover being indicated at Y Y, Fig. 5. Fig. 8 is an inside view of a blank having reenforced top and bottom edges. Fig. 9 is an inside view of a blank, the whole blank being re-enforced. Fig. 10

is an inside View of a gummed or pasted blank. Fig. 11 is an inside view of a re-enforced cover having its flaps turned back. Fig. 12 is an outside perspective view of a book provided with one of myimprovcd covers, showing how the book is supported 011 a shelf by the stiffened protecting-edges.

In making myimproved cover I take a sheet of Manila paper such as shown in Fig. 2of suitable size and of such proportionate length and height as will adapt it to fit the book to be covered. \Vhat are to be the top and bottom edges 1 of the cover maybe protected by a re-enforce of cloth or other material 1, (see Fig. 8,) or the whole cover may have such reenforce, as shown at 1 Fig. 9. The top and bottom edges 1 are folded over to the depth of about half an inch on the line a a, Fig. 2. The blank now has the form shown in Fig. 3. It is then folded 011 the line b b, so as to bring at the top and bottom edges the folded edges 1 together, thus making at those places four thicknesses of paper, as shown in Fig. 4. The continuous scams 0 c are now run from side to side of the cover through these four thicknesses at both top and bottom, (see Fig. 5,) whereby there are provided two pockets 4, adapted to receive the ordinary flexible or stiff covers 6 of a magazine or book 7, which, when inserted as shown in Fig. Gin the cover, are well protected by the unbroken stiffened edges 2 at top and bottom.

Fig. 7 illustrates the upper and lower protecting-edge of the cover.

In the modification shown in Fig. 1.0 the top and bottom edges, though doubled as before, are gummed or pasted.

It will be seen that the formation of the cover thus described adapts it to receive additional leaves 5, which may be gummed to one flap of the pockets 4 and serve to bear advertisements. The inner and outer flaps of the cover itself may also have advertisements printed upon them.

Having thus described my invention, the following is what I claim as new therein and desire to secure by Letters Patent:

1. The double cover formed integral with folded edges at the top and bottom folded in 5 and having seams of stitching providing stiffened protecting'edges, substantially as described and shown.

2.
